I live in Ukraine too, tried three different ISP providers and still get 403 Forbidden error when accessing adobe forums.

This lasts for a couple of month now.

Trashing cookies does not help.

At the moment, I am writing this post using foreign proxy server.

Is there any way to fix this issue?

Is it likely that Ukraine is blocking Adobe Forums? Some countries don't like its citizens to get any knowledge from outside its territory. Ukraine could be one such country considering Russians still have indirect power over its leaders. God knows what will happen next year when Euro 2012 takes place. I hope the security will be tight enough for the players and spectators.
